ND2R10A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 1.0

The ND2R10A is a Neutral Density Filter with a diameter of 50 mm and a thickness of 2 mm, manufactured by Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal tool for various optical applications.

The filter is made of N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures high-fidelity light transmission, minimizing optical losses and distortions.

The ND2R10A features a front and back coating of THo ND10, a specialized coating that further enhances the filter's performance. This coating reduces surface reflections, increasing light transmission and improving the overall image quality.

The filter is designed with a thin lens shape and is mounted with an SM2-threaded mount, providing a secure and stable connection to your optical system. This mount is compatible with a wide range of Thorlabs components, offering flexibility and versatility in system design.

The filter's optical density is 1.0, which means it reduces the light intensity by a factor of 10. This makes it suitable for applications where a significant reduction in light intensity is required, such as high-power laser applications or bright light sources.
